A study on low power wide area network technologies for internet of things

Abstract

LPWAN is used when other networks are not good fit like Wi-Fi, Zig bee, Bluetooth, because these networks are not suited for long-range applications as they consume lots of power and service, and hardware is also expensive. Hence LPWAN is suited for sending fewer amounts of data over long range keeping longer battery life. LPWAN is used in IOT because some of IOT applications require only fewer amounts of information data to be transmitted .eg parking garage sensor. In LPWAN, the end nodes can be placed even 10 km away from the gateway. Depending on IoT technology LPWAN data to be sent several times of a day and of data rate is 5000 bits per second.
